Formulaic. Forgettable. And that blurb is basically the whole story...

Considering that Kurt spent months (or about 2/3 of this short story) thinking that Shane was dating her sister (IMHO, he could easily remedy that situation simply by, oh I don't know, making some sort of comments to his sister at least, to confirm Shane's status) ... I was lucky that this one was short. Or I would be heavily annoyed on the lack of communication.
